Description

Technical Field

[0001] The invention relates to the technical field of concrete curing equipment, in particular to a concrete spraying curing device and a curing method thereof. Background Art

[0002] Concrete is a building material prepared by mixing cement, aggregate, water and some admixtures and admixtures in a certain proportion. It has high compressive strength and good durability, strong plasticity and relatively economical cost. It is widely used in house construction, bridge engineering, road paving and water conservancy facilities.

[0003] When concrete is solidifying, the cement in it will produce a hydration reaction. When the air is relatively dry and hot, the water in the concrete will evaporate quickly, causing the efficiency of the concrete hydration reaction to decrease or stop, resulting in a decrease in the strength of the concrete. In addition, dry and hot air will also cause the surface of the concrete to shrink rapidly and cause cracking problems. At the same time, the hydration heat inside the concrete is difficult to dissipate in time, resulting in a temperature difference between the inside and outside of the concrete and further cracking problems.

[0004] Therefore, after the concrete pouring is completed, the concrete needs to be sprayed with water in time to replenish the humidity on the concrete surface and in the air, and to reduce the temperature of the concrete and the surrounding air, so that the concrete can fully complete the hydration heat and discharge the heat to prevent the formation of cracks.

[0005] In bridge engineering, concrete spraying maintenance is usually carried out manually using a spray bottle or a water pipe. This maintenance method is extremely ineffective, requires a lot of manual labor, and the efficiency and effect of spraying are difficult to guarantee. It is impossible to maintain a large area of ​​concrete at the same time, which easily leads to problems such as untimely and incomplete maintenance. Summary of the invention

[0016] The present invention also provides a curing method for a concrete spray curing device, comprising the following steps: S1: First, place the water supply equipment in the vacant layer where the internal frame support system has been dismantled, then lay the main pipe and branch pipe in the construction layer and on the top surface where concrete pouring has been completed, and connect the main pipe with the water supply equipment; S2: Install an inner wall spray mechanism in the construction layer, install an outer wall spray mechanism at a position corresponding to the construction layer on the external frame protection system, and then install a top surface spray mechanism on the top surface of the construction layer. Finally, connect the inner wall spray mechanism, the outer wall spray mechanism and the top surface spray mechanism to the branch pipe; S3: When the air temperature and humidity reach the concrete spraying and curing adjustment, the electric control valve opens, and the water supply equipment senses the water supply demand and supplies water to the main pipe. The water flows through the main pipe and the branch pipe into the inner wall spray mechanism, the outer wall spray mechanism and the top spray mechanism, and then sprays and maintains the inner and outer sides and the top surface of the concrete wall of the construction layer. After the curing work reaches the set time, the electric control valve closes, and the water supply equipment loses the water supply demand and stops supplying water to the main pipe.

[0017] Compared with the prior art, the present invention provides a concrete spray curing device and a curing method thereof, which have the following beneficial effects: 1. By setting up inner wall spray mechanism, outer wall spray mechanism and top surface spray mechanism, when the temperature and humidity in the air reach the requirements of concrete maintenance, the branch pipe is opened through the electric control valve, and then the water supply equipment senses the water supply demand and delivers spray water to the main pipe and branch pipe. The spray water enters the inner wall spray mechanism, outer wall spray mechanism and top surface spray mechanism through the branch pipe, and sprays the water on the inner wall, outer wall and top surface of the concrete to replenish water and cool the concrete surface to prevent the problem of concrete cracking. The spraying process is completed automatically, and can be automatically opened and closed under timing, quantity and set conditions, which greatly reduces the labor intensity of spray maintenance workers and can ensure that the effect of spray maintenance is controllable.

[0018] 2. By setting up a reciprocating component and a driving component, the driving component can use the water flow to rotate and drive the reciprocating component to move, and the reciprocating component can convert the rotational power into a linear reciprocating motion and drive the inner wall sprinkler to move horizontally. The inner wall sprinkler uses its own reciprocating motion to continuously change its position, avoiding the problem that the fixed setting of the inner wall sprinkler will be blocked by the vertical poles of the inner frame support system, ensuring that the inner wall can be sprayed and maintained comprehensively.

[0019] 3. By setting up a rotary spraying assembly, the rotary spraying assembly can be driven by the water flow to rotate, and the water flow can be thrown out during rotation, so that the water flow is dispersed to the top surface, thereby achieving the effect of spraying and curing the concrete top surface. Because the concrete top surface is not blocked by the wall, the airflow and wind speed are relatively large. The water droplets sprayed by traditional nozzles have a small particle size and are easily affected by the airflow, resulting in uncontrolled spraying position. The method of using rotation to throw out the water flow has a lower height and fits the top surface on the one hand, and the larger particle size of the water droplets can resist the blowing of the airflow on the other hand.

[0020] 4. By setting up an angle adjustment component, the angle adjustment component can adjust the vertical angle and horizontal angle of the exterior wall sprinkler through the diverter pipe, so that the exterior wall sprinkler can be reasonably adjusted according to the position of the exterior wall, and when the vertical pole of the external frame protection system is not in the center of the exterior wall, the exterior wall sprinkler can still maintain a good targeted spraying effect, so that this system can adapt to a variety of installation environments.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1 See also Figure 1 to Figure 10 A concrete spray curing device, comprising a water supply device 1, an inner wall spray mechanism 4, a top spray mechanism 5 and an outer wall spray mechanism 6, characterized in that: the water supply device 1 is located in a vacant layer 11 where the main body construction is completed, the inner wall spray mechanism 4 is located in a construction layer 9 where concrete pouring is completed, and staggered from an inner frame support system 8, the top spray mechanism 5 is located on the upper top surface of the construction layer 9, and the outer wall spray mechanism 6 is located on an outer frame protection system 10 of the outer ring of the building; By utilizing the water supply equipment 1 to pressurize and transport temporary construction water, and then the inner wall spraying mechanism 4, the outer wall spraying mechanism 6 and the top surface spraying mechanism 5 to spray the curing water on the inner wall, outer wall and top surface of the concrete, a concrete spraying curing system is formed to achieve the purpose of replacing manual concrete spraying curing work, thereby reducing the workload of manual spraying curing, and setting time, quantity, temperature and humidity detection equipment in the system, so that the system can work automatically under the set conditions and ensure the efficiency and quality of curing.

[0034] The side of the water supply device 1 is provided with a main pipe 2 laid on the inner side and outer top surface of the construction layer 9, and the main pipe 2 is connected with a branch pipe 3 connected with the inner wall spray mechanism 4, the top spray mechanism 5 and the outer wall spray mechanism 6, and the branch pipe 3 is provided with an electric control valve 7; By using the main pipe 2 and the branch pipe 3 to realize the connection between the water supply equipment 1 and the inner wall spray mechanism 4, the outer wall spray mechanism 6 and the top surface spray mechanism 5, the maintenance water can be delivered and sprayed in time, and the electric control valve 7 can be used to control the inner wall spray mechanism 4, the outer wall spray mechanism 6 and the top surface spray mechanism 5 to be opened and closed separately, so as to achieve regional and targeted spray maintenance effects. For working surfaces with greater maintenance requirements, such as the windward side and the sunny side, the maintenance spraying time can be increased to meet the needs of concrete maintenance. For working surfaces with less maintenance requirements, such as the leeward side and the shady side, the maintenance spraying time can be reduced, so as to meet the maintenance requirements and reduce the consumption of water resources; It is also necessary to further explain the materials of the main pipe 2 and the branch pipe 3, including but not limited to hard pipes, soft pipes, metal pipes and plastic pipes. The specific materials, laying positions and connection methods need to be reasonably set according to the water supply head, water supply volume and coverage range.

[0035] The water supply device 1 includes a mobile platform 101 with a built-in driving device, a water supply pump 102 arranged on the mobile platform 101 and connected to the main pipe 2, a water storage tank 103 arranged on the mobile platform 101 and connected to the water supply pump 102, and a frequency conversion cabinet 104 connected to an external power supply for controlling the start and stop of the water supply pump 102. The frequency conversion cabinet 104 is also connected to a pressure gauge 105, and the pressure gauge 105 is arranged on the main pipe 2; In the present invention, a water tank 103 and a pressure gauge 105 are provided. The water tank 103 can be used to store construction water, and the water supply pump 102 can be pressurized before being transported into the main pipe 2. In this way, the demand for spraying maintenance can be guaranteed when the water pressure of the construction water is insufficient. The pressure gauge 105 can detect the current water pressure of the main pipe 2 and feed it back to the frequency conversion cabinet 104. The frequency conversion cabinet 104 can be used to control the water supply pump 102 to achieve the purpose of constant pressure water supply.

[0036] The inner wall spray mechanism 4 includes a tripod 401, a connecting pipe 402 and an inner wall spray head 406. The connecting pipe 402 is arranged on the side of the tripod 401, and one end of the connecting pipe is connected to the branch pipe 3, and the other end is connected to the inner wall spray head 406. The inner wall spray head 406 faces the inner wall body. In this embodiment, a tripod 401 is used to support the inner wall sprinkler 406, so that the inner wall sprinkler 406 can be placed in the construction layer 9, and can perform comprehensive spraying maintenance operations on the surrounding walls, and can freely place its own position to facilitate laying work.

[0037] Example 2 refer to Figure 3~Figure 5 Specifically, a driving component 403 that rotates using water flow and a reciprocating component connected to the driving component 403 for driving the inner wall sprinkler 406 to reciprocate are provided on the tripod 401. The water inlet end of the driving component 403 is connected to the connecting pipe 402, and the water outlet end is provided with a hose that is connected to the inner wall sprinkler 406. In this embodiment, the inner wall sprinkler 406 is connected by using the driving component 403 and the reciprocating component 404. When the spraying work is performed, the spray water in the branch pipe 3 enters the driving component 403 through the connecting pipe 402, pushing the driving component 403 to rotate, and then the spray water enters the inner wall sprinkler 406 through the hose and is sprayed out. When the driving component 403 rotates, the inner wall sprinkler 406 is driven to move back and forth in a straight line through the reciprocating component 404. The inner wall sprinkler 406 constantly changes its position during spraying. On the one hand, it can increase the coverage range of the inner wall sprinkler 406 and increase the spraying effect. On the other hand, it can avoid the problem that the inner wall sprinkler 406 sprays at a fixed position and is partially blocked by the vertical poles of the inner frame support system 8. The reciprocating movement of the inner wall sprinkler 406 ensures the comprehensiveness of the spraying maintenance.

[0038] The driving assembly 403 includes a guide shell 4031 disposed on the tripod 401, a fan blade 4033 rotating in the guide shell 4031, a reduction gear set 4035 penetrating the guide shell 4031 and connected to the fan blade 4033, an output shaft 4036 disposed on the reduction gear set 4035 and connected to the reciprocating assembly 404, and a fixing frame 4037 disposed on the side of the guide shell 4031 for supporting the reciprocating assembly 404. A water inlet 4032 and a water outlet 4034 are disposed on the side of the guide shell 4031. The water inlet 4032 is communicated with the connecting pipe 402, and the water outlet 4034 is communicated with the inner wall hose 405. By receiving the thrust of the water flow through the fan blades 4033 and then transmitting the power to the reduction gear set 4035 through the output shaft 4036, the effect of utilizing water flow to drive is achieved, the cost of electric drive equipment is saved, and there is no need to lay lines. In addition, by utilizing the reduction gear set 4035 to transmit the rotational power to the reciprocating parts, the rotation speed of the output shaft 4036 can be reduced and its output torque can be increased. On the one hand, the water flow speed required to drive the fan blades 4033 can be reduced, and on the other hand, the reciprocating parts can be prevented from moving at too high a speed and frequency, which would cause the tripod 401 to easily shake and tip over.

[0039] The reciprocating assembly 404 includes a fixing plate 4041 provided with a positioning groove 4046 on a fixing frame 4037, a rotating disk 4042 provided on the fixing plate 4041 and connected to the output shaft 4036, a pin 4043 eccentrically connected to the edge of the rotating disk 4042, a sliding rod 4044 provided with a notch inside and slidably matched with the pin 4043, and positioning pins 4045 provided at both ends of the lower part of the connecting rod and slidably matched with the positioning groove 4046, and both ends of the sliding rod 4044 are connected to the inner wall sprinkler 406; The rotation of the turntable 4042 drives the pin shaft 4043 to make a circular motion, and then the pin shaft 4043 pushes the sliding rod 4044 to move, and the sliding rod 4044 makes a linear reciprocating motion with the cooperation of the positioning pin 4045 and the positioning groove 4046, thereby realizing the purpose of converting the rotational power into a linear reciprocating power, and achieving the purpose of driving the inner wall sprinkler 406 to continuously change its own position.

[0040] Example 3 refer to Figure 6~Figure 7 The specific top surface spraying mechanism includes a base 501, a support frame 502 and a curved pipe 503.

Compared with the traditional mist nozzle, the interference of airflow blowing can be reduced.

[0041] The rotary spray assembly 504 includes a flow-limiting shell 5041 disposed on the curved pipe 503, a hollow rotating shaft 5042 is rotatably connected in the flow-limiting shell 5041, an impeller 5044 is disposed outside the hollow rotating shaft 5042, a drainage hole 5045 located above the impeller 5044 is opened on the side of the hollow rotating shaft 5042, the top end of the hollow rotating shaft 5042 penetrates the flow-limiting shell 5041 and is connected to a spray pipe 5043, and the front end of the spray pipe 5043 is bent; The water flows into the flow limiting shell 5041 and flows upward. When the water flows, it will push the inclined impeller 5044 to rotate. The impeller 5044 drives the spray pipe 5043 to rotate through the hollow shaft 5042. When the water flows to the drainage hole 5045, the water flows into the hollow shaft 5042 through the drainage hole 5045, and is then sprayed out by the spray pipe 5043, so as to achieve the purpose of spraying the water. In addition, the water flow rate can be controlled by the electric control valve 7, and then the rotation speed of the spray pipe 5043 can be controlled, so as to achieve the purpose of spraying far away when the spray pipe 5043 rotates quickly and spraying near when it rotates slowly.

[0042] Example 4 refer to Figure 8~Figure 9 The specific external wall spray mechanism 6 includes two mutually hinged arc-shaped clamping plates 601, a gripping rod 602 is provided on the side of the arc-shaped clamping plate 601, a shunt pipe 606 is provided on the end face of the gripping rod 602, an external wall hose 604 connected to the branch pipe 3 is provided on the side of the shunt pipe 606, and external wall sprinklers 607 are provided at both the upper and lower ends of the shunt pipe 606, and a magnet 603 adsorbed on the external frame protection system 10 is provided on the inner side of the arc-shaped clamping plate 601; The arc-shaped clamping plate 601 can be opened and closed under the drive of the holding rod 602, and use its own arc-shaped surface to fit on the vertical pole of the external frame protection system 10, and then use the magnet 603 provided on the inner side of the arc-shaped clamping plate 601 to adsorb on the external frame protection system 10 to achieve a fixing effect, so that the external wall nozzle 607 on the end face of the holding rod 602 can be directed to the concrete external wall to achieve the purpose of spraying and maintaining the concrete external wall. In addition, the use of the magnet 603 for adsorption is only one implementation method of this embodiment, and a coil spring can be further added at the hinge of the arc-shaped clamping plate 601 to increase the clamping force of the arc-shaped clamping plate 601.

[0043] An angle adjustment assembly 605 for providing angle adjustment for the shunt tube 606 is provided on the holding rod 602. The angle adjustment assembly 605 includes a support sleeve 6051. The support sleeve 6051 is horizontally slidably and rotatably connected to the end surface of the holding rod 602. A first friction disc 6052 is provided at one end of the support sleeve 6051 located inside the holding rod 602. A first spring 6053 is provided between the back of the first friction disc 6052 and the inner wall of the holding rod 602. The support sleeve 6051 is vertically slidably and rotatably connected to the shunt tube 606. A second friction disc 6055 is provided at a position on the outer side of the shunt tube 606 located inside the support sleeve 6051. A second spring 6054 connected to the inner wall of the support sleeve 6051 is provided on the second friction disc 6055. In this embodiment, the first spring 6053 applies a thrust to the first friction disk 6052, and the second spring 6054 applies a thrust to the second friction disk 6055, so that the support sleeve 6051 is normally supported by the first friction disk 6052 and maintained in a fixed position, and the shunt pipe 606 is supported by the second friction disk 6055 and maintained in a fixed position. When the angle of the support sleeve 6051 needs to be adjusted, the support sleeve 6051 is pressed inward to separate the friction disk from the inner wall of the gripping rod 602, and then the support sleeve 6051 can be rotated freely. 51. After adjusting to the required position, release the pressure on the support sleeve 6051, so that the first spring 6053 squeezes the first friction disk 6052 onto the inner wall of the holding plate. When it is necessary to adjust the angle of the shunt tube 606, lift the shunt tube 606 upward so that the shunt tube 606 drives the second friction disk 6055 to separate from the inner wall of the support sleeve 6051. After rotating to the required position, release the shunt tube 606. The shunt tube 606 and the second friction disk 6055 are fitted into the support sleeve 6051 under the push of the second spring 6054.

[0044] Example 5 The present invention also provides a curing method for a concrete spray curing device, comprising the following steps: S1: firstly, the water supply equipment 1 is placed in the vacant layer 11 where the inner frame support system 8 has been dismantled, and then the main pipe 2 and the branch pipe 3 are laid in and on the top surface of the construction layer 9 where concrete pouring has been completed, and the main pipe 2 is connected to the water supply equipment 1; S2: Install an inner wall spray mechanism 4 in the construction layer 9, install an outer wall spray mechanism 6 at a position corresponding to the construction layer 9 on the external frame protection system 10, and then install a top surface spray mechanism 5 on the top surface of the construction layer 9, and finally connect the inner wall spray mechanism 4, the outer wall spray mechanism 6 and the top surface spray mechanism 5 to the branch pipe 3; S3; when the temperature and humidity of the air reach the adjustment for concrete spraying and curing, the electric control valve 7 opens, and the water supply equipment 1 senses the water supply demand and supplies water to the main pipe 2. The water flows through the main pipe 2 and the branch pipe 3 into the inner wall spray mechanism 4, the outer wall spray mechanism 6 and the top surface spray mechanism 5, and then sprays and maintains the inner and outer sides and the top surface of the concrete wall of the construction layer 9. After the curing work reaches the set time, the electric control valve 7 is closed, and the water supply equipment 1 loses the water supply demand and stops supplying water to the main pipe 2.

[0045] The maintenance method of the concrete spraying maintenance device provided in this embodiment can be laid in advance, that is, the water supply equipment 1 can be set up in advance before the concrete pouring work, and then the main pipe 2, branch pipe 3 and inner wall spraying mechanism 4 in the construction layer 9 can be installed and laid. At the same time, the outer wall spraying mechanism 6 can be installed on the external frame protection system 10 and connected with the main pipe 2 and branch pipe 3 in the construction layer 9. When the concrete pouring completion surface is ready for people to work, the main pipe 2, branch pipe 3 and top surface spraying mechanism 5 on the top surface are laid. Since there is no interference from the frame on the top surface of the concrete, the laying efficiency of the main pipe 2, branch pipe 3 and top surface spraying mechanism 5 is relatively high, so that the concrete can be sprayed and maintained in time, greatly improving the maintenance efficiency.

[0046] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
